Four species of pusley (Richardia L.) are widespread and common weeds in Florida vegetable and strawberry production. We refer to the native plant Richardia scabra L. as Florida pusley. This discrimination is necessary because these species are often referred to collectively as Florida pusley due to overlapping distributions, similar growth habits and leaf morphologies, and difficulty identifying without the presence of fruit. This new 6-page publication of the UF/IFAS Horticultural Sciences Department describes the different pusley species and provides management options for strawberry, pepper, cucurbits, and tomato. Written by Shaun M. Sharpe, Nathan S. Boyd, Chris Marble, and Shawn Steed.
This new 4-page article provides an overview of a group of crop production materials termed “plant biostimulants,” which are frequently promoted as environment-friendly alternatives to chemical-based products. It explains their regulatory status and presents an overview of the most popular materials (e.g., beneficial fungi, seaweeds, and silicon) and their effects on plants. Written by Ute Albrecht and published by the UF/IFAS Horticultural Sciences Department.
El potencial económico en la producción comercial para el cultivo de granadas en Florida es actualmente desconocido en este momento. La investigación científica continúa sobre la posibilidad de encontrar variedades de granadas que puedan crecer en Florida. Las condiciones ambientales, con una alta temporada húmeda en la Florida, y un clima caluroso, son factores que son favorables para las enfermedades en las granadas y eso reduce la calidad de esta fruta, especialmente para las variedades de temporada tardía como la variedad ‘Wonderful’. ‘Wonderful’ es el principal cultivar comercial que se originó en la Florida. Para reducir las enfermedades y evitar la competencia de comercialización con las granadas de California, la investigación para la producción de granadas en la Florida debe centrarse en buscar variedades de temporada temprana que puedan cosecharse en julio y agosto. This six-page document is the Spanish translation of HS44, The Pomegranate.

The importance of protecting perishable foods from loss of quality during transport has long been recognized. Increased recognition of the importance of the transport link in the food distribution cold chain in securing the safety of perishable foods has more recently become as well recognized.
This updated edition reflects the dynamic changes and innovations in the handling and transportation of perishable foods. Some of these include improved insulation and air movement, microprocessors for more efficient refrigeration, expert systems to control the transport environment and conserve fuel energy, and the use of telematics to monitor and control the performance of refrigerated vehicles during transit. This edition includes descriptions and recommendations for food transported over the road and by rail in marine containers, as well as in railcars. This 214-page revision was written by J. K. Brecht, Steven A. Sargent, Patrick E. Brecht, Jorge Saenz, and Leonard Rodowick and published by the UF/IFAS Horticultural Sciences Department in cooperation with the USDA AMS Transportation Services Division.

While the desire to implement urban agriculture projects is growing in popularity, there is little information available to help Extension agents and interested citizens fully understand how to implement urban agriculture in their community. This new 11-page document provides an overview of key information required to establish an urban agriculture ordinance. Case studies from urban agriculture initiatives in Florida provide real-world examples of the required activities, potential challenges, and beneficial partners for implementing these initiatives. Resources related to the case studies and additional urban agriculture resources can be found at the end of the document, so that readers can find further information specific to their interests and needs. Written by Candace A. Spencer, Catherine G. Campbell, Anna Prizzia, and Liz Felter, and published by the UF/IFAS Horticultural Sciences Department.
Alpine strawberries (Fragaria vesca) produce edible and highly aromatic strawberries known for their excellent eating quality. The berries are fragile and not suitable for long-distance shipping, which inhibits trade on the international market but also provides an opportunity for growers catering to local markets and for homeowners interested in growing this unique and delicious strawberry. This 5-page fact sheet written by Alan Chambers and published by the UF/IFAS Horticultural Sciences Department describes yield and fruit quality for several varieties to guide potential growers. The results of this project are anticipated to benefit growers and homeowners looking to cultivate specialty alpine strawberries.
